Anyway! So the main reason I'm making this post is to ask for some details about beetleweights - I don't want to spend ages on this CAD if this isn't going to work from the beginning.
Can anyone recommend a nice torquey gearmotor for the walking mech? I see these 12v 25mm motors are popular, but apparently some are worse than others despite looking all the same. I'm after something with a slow speed, around 100rpm. I can't find any of the "good" plastic-backed 25mm motors with anything except a 1000 rpm gearbox - so I'm thinking of using these, although they are quite heavy.

I'm also wondering what sort of hdpe thicknesses people use on Beetles? I'm already over the weight limit - what is the lowest thickness I could scrape by on for chassis materials? I'm thinking that the legs will probably be hit and broken before the chassis of the robot will, so it could be pretty thin.
